Overview
Comment:Only log unlink() errors if the error is something other than SQLITE_IOERR_DELETE_NOENT. The error is still reported up the stack, it is simply not added to the sqlite3_log().

Strive to use posix_fallocate() rather than ftruncate() when posix_fallocate() is available. Ticket [5eaa61ea18]. check-in: 29980b08 user: drh tags: trunk

When available, use posix_fallocate() rather than ftruncate() to allocate space for mmap()ed -shm files, since posix_fallocate() gives an error if no disk space is available whereas ftruncate() is silent and leaves the system vulnerable to a SIGBUS upon first write to the mmap()ed region.

Change os_unix.c to propagate ENOENT errors back to sqlite as SQLITE_IOERR_DELETE_NOENT. Have SQLite ignore these where they are benign and propagate them back to the caller where they may indicate a file-system malfunction of some description. check-in: bed9c172 user: dan tags: trunk
